- the present invention relates to a card edge connector, and more particularly to a lower profile card edge connector.
- Cida 102217811U issued on May 9, 2012, discloses a card edge connector including an insulative housing, a row of first terminals and a row of second terminals.
- a first elastic portion of each first terminal extends forwardly from a first retaining portion to a first contacting portion without folding and a second elastic portion of each second terminal extends forwardly from a second retaining portion to a second contacting portion without folding.
- the first and second elastic portions both extend along a non-back folding line so as to reduce the height of the first and second terminals which can synchronously reduce the thickness of the card edge connector.
- An object of the present invention is to provide a lower profile card edge connector having more space used for receiving a row of lower terminals.
- a card edge connector for being retained into a notch of a print circuit board, comprising an insulative housing defining a central slot extending along a longitudinal direction, a first wall and a second wall located on the opposite sides of the central slot and a fitting portion extending downwardly into the notch from a bottom portion of the first wall, the fitting portion defining a plurality of first terminal slots and the second wall defining a plurality of second terminal slots.
- a plurality of first terminals are retained in the insulative housing and received in the first terminal slots, and a plurality of second terminals are retained in the insulative housing and received in the second terminal slots.
- each first terminal defines a first retaining portion received in the first terminal slot of the fitting portion and a first soldering portion extending out of the housing forwardly from the first wall
- each second terminal defines a second soldering portion rearwardly extending out of the housing.
- FIG. 1 is a perspective view of a card edge connector assembly including a printed circuit board and a card edge connector mounted on the PCB in accordance with the present invention
- FIG. 2 is another perspective view of the card edge connector assembly shown in FIG. 1 ;
- FIG. 3 is a partially exploded perspective view of the card edge connector assembly shown in FIG. 1 ;
- FIG. 4 is an exploded perspective view of the card edge connector assembly of FIG. 2 showing the card edge connector separated from the PCB;
- FIG. 5 is a cross-sectional view of the card edge connector assembly take along line 5 - 5 shown in FIG. 1 .
- a card edge connector assembly including a card edge connector 100 and a printed circuit board/motherboard 200 on which the card edge connector 100 mounted is disclosed in accordance with the present invention.
- the card edge connector 100 for accommodating an electrical card is used to be soldered on the motherboard 200 of an electronic device in order to achieve the electronic transmission between the electrical card and the motherboard 200 .
- This electronic device can be thinner laptop or other similar electronic products.
- the card edge connector 100 includes an insulative housing 1 , a plurality of first terminals 2 and a plurality of second terminals 3 retained in the insulative housing 1 .
- the insulative housing 1 is elongated shape and includes a first wall 11 and a second wall 12 opposite to the first wall 11 , a rear wall 13 connecting to the first wall 11 and the second wall 12 , and a pair of side walls 14 respectively located on two longitudinal ends of the first and second walls 11 , 12 .
- a narrow central slot 10 extends along a longitudinal direction of the connector is located between the first wall 11 and the second wall 12 for receiving the electrical card, and the central slot 10 defines a key 15 close to one of the side walls 14 to prevent the electrical card from being inserted into the central slot 10 in an incorrect direction.
- the first wall 11 forwardly projects beyond the second wall 12 so as to form an obliquely upward insertion port in the front of the central slot 10 .
- the first walls 11 and the second walls 12 are located at opposite sides of the central slot 10 respectively.
- the first wall 11 forwardly projects beyond the second wall 12 , which means that the length of the first wall 11 is different from the length of the second wall 12 in the front-to-rear direction so as to form an obliquely upward insertion port in the front of the central slot 10 to facilitate the obliquely insertion of the electrical card.
- a fitting portion 110 extends downwardly from the bottom portion of the first wall 11 and located in a notch or through opening 201 of the motherboard 200 , wherein the notch 201 is bounded by corresponding front, rear and side edge sections of the printed circuit board which surrounds the notch 201 , and the fitting portion 110 does not exceed the lower surface of the motherboard 200 .
- the fitting portion 110 defines a plurality of first terminal slots 111 running through the first wall 11 and opening to the central slot 10
- the second wall 12 defines a plurality of second terminal slots 121 opening to the central slot 10 and each offsets from a corresponding first terminal slot 111 in the longitudinal direction.
- Each second terminal slot 121 communicates with the central slot 10 and runs through the rear wall 13 to form a fixing slot 130 in the rear wall 13 .
- the plurality of first terminals 2 are assembled into the first terminal slots 111 of the first wall 11 .
- Each first terminal 2 defines a first retaining portion 21 received in the fitting portion 110 , a first contacting arm 22 extending rearwardly from the first retaining portion 21 , a first soldering portion 23 forwardly extending out of the first wall 11 and a first connecting portion 24 connecting with the first retaining portion 21 and the first soldering portion 23 .
- the first contacting arm 22 is resilient and has a first contacting portion 221 upwardly projecting into the central slot 10 .
- the first retaining portion 21 is disposed lower than a plane in which the first soldering portion 23 disposed, and the first soldering portion 23 is located between the first retaining portion 21 and the first contacting arm 22 in a vertical direction perpendicular to the front-to-rear direction and the longitudinal direction.
- the first soldering portion 23 extends outside of the insulative housing 1 to horizontally arrange adjacent to the notch 201 to be mounted on the motherboard 200 .
- the plurality of second terminals 3 are assembled into the second terminal slots 121 of the second wall 12 from the rear wall 13 in a rear-to-front direction.
- Each second terminal 3 defines a second retaining portion 31 received in the second terminal slots 121 , a second contacting arm 32 bending and extending forwardly from the second retaining portion 31 , a second soldering portion 33 extending rearwardly from the second retaining portion 31 and a second connecting portion 34 received in the fixing portion 130 and connecting with the second retaining portion 31 and the second soldering portion 33 .
- the second contacting arm 32 is resilient and has a second contacting portion 321 projecting into the central slot 10 , the second retaining portion 31 is higher than the second contacting arm 32 and the second soldering portion 33 in the vertical direction, and the second soldering portion 33 rearwardly extends outside of the insulative housing 1 for locating on the motherboard 200 to adjacent the notch 201 .
- the first terminal 2 can be elastic deformed downwardly in the first terminal slot 111 when the electrical card is inserted into the central slot 10 .
- the fitting portion 110 of the first wall 11 and the first retaining portion 21 of the first terminal 2 are both located in the notch 201 so that the first contacting arm 22 of the first terminal 2 can produce larger elastic force with less elastic deformation so as to achieve a larger clip force on the electrical card. It can increase the receiving space of the first terminal 2 without increasing the height of the card edge connector 100 so that the card edge connector 100 is adapted for miniaturization trends.
- the card edge connector 100 can be mounted onto the motherboard 200 with the front edge 113 located on a side edge of the notch 201 to set the fitting portion 110 into the notch 201 .
- the rear edge 114 of the rear wall 13 can be also set step-shaped to mount on another side edge of the notch 201 of the motherboard.
